Summary: Prototype of API to allow MyRocks to override default Mutex/CondVar used by transactions with their own implementations. They would simply need to pass their own implementations of Mutex/CondVar to the templated TransactionDB::Open(). Default implementation of TransactionDBMutex/TransactionDBCondVar provided (but the code is not currently changed to use this). Let me know if this API makes sense or if it should be changed Test Plan: n/a Reviewers: yhchiang, rven, igor, sdong, spetrunia Reviewed By: spetrunia Subscribers: maykov, dhruba, leveldb Differential Revision: https://reviews.facebook.net/D43761
